The current situation: As we can see right now, there are more than 20.9 million accumulative confirmed cases across the world, of which over 7.4 million have not been cured yet. The whole world is fighting aganist the highly contagious virus that is threatening us all and we can’t assure when the turning point will be, but, please, stay calm and stay safe, we will definitely beat it. Something about the visualization: For the interactive plots and quick search datatable, the orignal ideas are from jiaying-Wu: https://jiaying-wu.github.io/COVID-19.github.io/ Framework of this storyboard: I simply broke it into 4 parts, which are in order a brief introduction of the storyboard, data wrangling process, analysis and visualization of COVID-19 globally in general, analysis and visualization of COVID-19 in some representative countries/regions.
The interactive 3D global map shows us vividly thoes who are suffering the most. You can rotate it to see the whole picture.
Over time, both mortality and survival rates increase.
We can see the mortality rate is incresing slowly but steadily, which can’t be a good sign. The recovery rate, however is unstable by the time, but we can see it has been going up obviously from April.
The mortality rate and recovery rate are not related, but are related to new cases, indicating that the more cases there are, the more likely it is to be detrimental to recovery.
We can see that the US has the most confirmed cases and the Iran has the least. On the one hand, it indicates that the US has a high population density and a high disease transmission rate, but it also shows that the US medical system is developed and has the ability to detect viruses.
The death rate in the United States is also the highest, indicating that the public healthcare system in the United States is in crisis, resulting in many people dying without treatment.
From this graph, we can see that the mortality rate of Brazil is lower than that of the United States (the previous graph), and the recovery rate is higher than that of the United States. We can conclude that the medical level of Brazil is higher than that of the United States
It seems like that all the others’ recovery rate have gradually been rising since March apart from UK’s recovery rate almost closing to zero from March.
It clearly tells us all the six countries’ mortality rates go up roughly over time, although Russia didn’t show significant trend.
Datatable for quick search of the provice you are interested in.
We can see that the number of confirmed cases in China has been very slow since April, indicating that the epidemic has been controlled.
We can see that the number of deaths in China has not increased after April, indicating that the medical system has played a huge role.
We can see that the new cases are stabilizing.
We can clearly see that the cure rate in China is very high, indicating that the government has made tremendous contributions.
We can see that no matter which city, there are almost no deaths, and the cure rate is almost equal to the number of confirmed cases, indicating that the virus has weakened its harm to people and the disease has been controlled.
In a word, here we analyzed the COVID-19 in different regions, and compared their mortality, recovery rate, and new number. We focused on the COVID-19 in China, and concluded that China has made great contributions in combating COVID-19.
